Introduction

This document describes how to configure the BFD Protocol in Secure Firewall Management Center (FMC) running 7.3 and later.

Requirements

Cisco recommends that you have knowledge of these topics:

- Border Gateway Protocol (BGP) protocol

- Bidirectional Forwarding Detection (BFD) concepts

Components Used

The information in this document is based on these software and hardware versions:

- Secure FMC Virtual version 7.3.1

- BGP configured in Cisco Secure Firewall Threat Defense (FTD) with Cisco Secure FMC running version 7.3 and later

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.

Background Information

BFD is a detection protocol designed in order to provide fast-forwarding path failure detection times for all media types, encapsulations, topologies, and routing protocols.

Configure

Refer to these steps for BFD configurations in FMC running versions 7.3 and later.

Step 1. Navigate to the Devicesbutton on the top and click the Device Managementbutton.

Step 4. Select the Interface in which the BFD protocol is going to be configured, and create a new template by clicking the + button.

Note: The echo feature is only available in Single-Hop mode.

Step 6. Choose the template you already created in the earlier step and click  OK.

Step 7 (Optional). For BFD fall over, click the IPv4 or IPv6button depending on your configuration of BGP on the left column. Choose theNeighbor tab, and then click the edit pencil on the right for the desired neighbor address.

Verify

Verify the BFD configuration and the status directly on the CLI session with these commands:

> system support diagnostic-cli

Attaching to Diagnostic CLI ... Press 'Ctrl+a then d' to detach.

Type help or '?' for a list of available commands.
